joint military drills. >> this is al jazeera america live from new york city. i'm richelle carey. we're a day away from the next contest in the presidential race. in michigan is the big prize. the democrats were there last night clashing in a bitter and often heated debate. the water crisis and the state's economy were front and center. bernie sanders with several key victories tried to turn the heat up on hillary clinton, but she did hit back. >> ladies and gentlemen, the democratic candidates for president of the united states. >> it was their seventh debate. the venue, flint, michigan. the focus, the toxic water crisis. the candidates wasted no time sounding off. >> i believe the governor of this state shut understand that

his dereliction of duty is irresponsible, and he should resign. >> it is raining lead in flint and the state is der recollect in not coming forward with the money required. >> and both were challenged on the failings of the environmental protection agency. >> people should be fired. how far up it went, i don't know. but as far as it goes they should be relieved because they failed this city. >> the president sai, i would fire anyone who knew what was happening and did not act appropriately. >> the candidate were grilled from every direction. some questions were pointed. >> as presidential clin candidate first visit to flint was just a month ago. >> that's not quite create. i was here before that. >> jobs were high on the list of concerns among michigan voters and with bad trade deals partly to blame. sanders saw his opening and

pounced. >> secretary clinton supported virtually every one of these disastrous trade agreements written by corporatement america. >> he voted against the money that ended up saving the auto industry. i think that is a pretty big difference. >> sanders countered by saying he did not support the bailout because wall street was to blame and kept up his attack on clinton for her wall street ties. the two clashed on corporate subsidies. sanders had to explain why he sided with senator cruz on the issue. >> boeing and other big companies get support just like they are competitors do from the companies that they are from in the countries that provide the support. >> isn't it tragic that these large multi national corporations making billions of dollars a year shutting down in america, going to china, going to mexico, all absolutely they need a hand out from the american middle class--i don't think so.

>> the debate took a poignant turn when the father of 14-year-old abigail, a survivor offer shooting in kalamazoo, asked about gun control. >> if you hold manufacturers liability, if they understand that the guns are getting into the hands of criminals, of course they should be held liable. but if they're selling a product to a person who buys it legally, you're talking about the end of gun manufacturing in america. i don't agree with that. >> no other industry in america has absolutely-- >> senator-- >> the candidates were also asked about race both invoked their civil rights records, but both supported a 1994 crime bill that led to higher levels of incarceration that disproportionately affected blacks. >> boast oboth of the candidates are continue to go candidate in michigan today. at this point hillary clinton

has a commanding lead over sanders. diane estherbrook, al jazeera, flint, michigan. >> the latest delegate count gives clinton the bigger lead. if you easy in the superdelegates clinton has half the delegates needed to lock in the nomination. marco rubio is hoping for momentum. he got more than 50% of the vote manying that he gets all 23 delegates. but he still lags far behind donald trump and ted cruz in the delegate count. trump and cruz split the other delegates. tomorrow four states will have their say on the republican nomination. lincoln mitchell explains this now. it seemed for a while that donald trump was almost a forgone conclusion because of the momentum he had, the energy, but when you look at the numbers ted cruz is not that far behind.

>> primaries are about. delegate counting. donald trump has won about 44% the delegates. remaining on that pace leads to a brokered convention. now there are some things that will change. beginning on march 15th a lot more winner will take all or winner take almost all or if you win a congressional district you get all the delegates. if you're wannin winning you can pile up the delegate counts. however, on march 15th when we shift to that direction on the republican side and he loses ohio and florida the mountain gets very steep very quickly. it is possible--we don't quite have enough information but he's not winning--right now he's not on track, but the rules will change in a way that will favor him. on the other hand, if he loses a few more states we could broker a convention. >> talk about the math for marco rubio, it is not good. >> no, the math for marco rubio

winning the nomination outright is none existent. he has to catch on fire politically. but he could play a spoiler role. he could bring his own state in. he might pick up a few states long the way. if you're marco rubio you have to think about the long term. could you be a running mate? could you put together a convention, something like that, but in 2020 could he come out of this not come only coming out as a well-spoken guy, but can he play a constructive role that go can out and win votes. if he doesn't win in florida what is the story he tells in 2020 if he wants to run again? >> let's talk about the democratic side, what jumped out at you in this debate over the weekend. has bernie sanders turned any kind of corner? >> you really saw the different styles here. there is a real choice here. persony sanders, does--bernie

sanders does speak about an issue. and there was a time when that framework really worked. he said you can have my speeches. that resonates with voters. on the other hands when they got into the weeds of some of the issues,ation and most notably guns. >> what happened there. >> what happens is bernie sanders does not have a great record on guns. there is no way to slice that. hillary clinton is right. gun manufacturers, if you don't hold them accountable you'll have a very hard time regulating guns. what do the american people think about this? that's more complex. but in a democratic primary where people do support gun regulation, hillary clinton has the better position and articulated it better. >> and the nra jumped on what bernie sanders had to say saying yes, they do want to shut down the gun industry. >> at one point hillary clinton said something like that in an nra talking point, but this is not something that you want to say in a democratic primary.

>> what are the next states coming up. >> one is mississippi. i would expect a large hillary clinton win, 2-1, maybe more, maybe less but a big decisive win. these are not winners take all. bernie sanders is leaving delegates on the table. leaving superdelegates aside. that's a whole other issue, hillary clinton has won 58% of the earned delegates. if she continues on this pace she wins with no superdelegates. i think she'll get 58% of the delegates. in mississippi, and i expect more. also it's the first of what what we might call a northern industrial state. it's a state with industry, union members and a large african-american population. it doesn't have a large latino population like california and new york, but it has a huge african-american population. hillary clinton will likely win there, but it's not a give.

but bernie sanders has to be competitive. he can't lose michigan-60-40. if he loses michigan, 60-40, then what does he say in ohio and illinois. you see these delegate-rich states moving to hillary clinton, and then bernie sanders does not have a path to the nomination. >> we appreciate it. all right, flags are in half-staff in honor of former first lady nancy reagan. president obama ordered the flags lowered at the white house, federal buildings and embassies out of respect for her. the 94-year-old died at her moment in los angeles on sunday. she was one of ronald reagan's closest advisers, and of course she was the love of his life. the two were married for 52 years. jennifer london is live in simi valley, california. the site of the reagan presidential library. what do we know about the

funeral of mrs. reagan? >> well, hello to you, richelle. we know that funeral plans are under way. she will be buried here at the ronald reagan presidential library along side her husband, who passed in june 2004. at this point the library is not revealing a lot of details regarding the funeral and burial, but i did have a chance to speak with a spokeswoman earlier today. she said later this afternoon they said they will reveal the details. she did tell me that nancy reagan played a critical role. she planned every detail of her service from selecting the pallbearers to the guests to the speakers. the library is closed. it closed yesterday and will remain closed until two days after the service and the burial, which will also be closed to the public. but we are told that members of the public will have a chance to pay their final respects to nancy ray gran. nancy reagan asked that in lieu of flowers that contributions and donations be made to the library of which she was really

considered a driving force behind. she played a critical role in many of the exhibits and she would come to the library every year to mark the anniversary of the passing of her husband ronald reagan. again, she'll be buried along side him later this week. richelle, in a half hour there will be a flag lowering ceremony outside of the library. >> jennifer, tell us more about how nancy reagan changed the role of first lady. >> well, she redefined the role of the first lady. it was not just her involvement in public campaigns, the war on drugs, the just say no campaign. it was also her involvement inside the white house. nancy reagan was known to play a critical role in the hiring and firing of key staff members and cabinet members. >> all right, jennifer london live for us in simi valley, california. jimmy carter said he has

turned the corner in his battle against cancer. he said he does not need any more treatment. he reveal thad doctors had discovered four small lesions on his brain. the combination of therapy and radiation ended last month. carter, who is 91, said he'll continue to get checkups in case the cancer returns. new threats from north korea this morning it has promised to launch strikes on the u.s. and south korea. the threat comes as the u.s. and south korea hold joint military drills today. 200,000 troops on the south korean side and 70,000 troops from the u.s. >> there are some who express concerns whether this is tightening the concerns and the tensions. but i think that kind of view would b would have merit if

north korea continues to express its desire for peace and prosperity for those their people, which is not the case. and if they're talking about just regular conventional war, conventional military build up. which is not the case and a country that is expressing desire for self defense, which is not the case the sanctions were result of recent long range rocket launch and nuclear tests. just ahead, a first for mac users. ransom wear effecting apple computers. and brace for more wet weather.
